I saw your message on tech-pkg%netbsd.org@localhost, recognized your name and sbase.  

That was some time after I successfully cross-compiled Busybox for Linux from both FreeBSD and NetBSD.

Toybox no good, only partly because of all those #!/bin/bash in scripts.

I built some toolchains, some but not all successfully, from Rich Felker's musl-cross-make 

git remote -v
origin  https://github.com/richfelker/musl-cross-make.git (fetch)
origin  https://github.com/richfelker/musl-cross-make.git (push)

I looked at Oasis, which I follow via git, am still trying to figure if it could build from NetBSD or FreeBSD.

I am not sure if this list is appropriate or if this thread should go to offlist email.

I would want something that would be able to build gcc and the Linux kernel.

Otherwise, how do you update Oasis from itself, if cproc is not up to building gcc or the Linux kernel?

I am now on NetBSD 9.99.82 for both amd64 and i386.

I see there is also a newer musl-cross-make:

git remote -v
origin  https://git.zv.io/toolchains/musl-cross-make.git (fetch)
origin  https://git.zv.io/toolchains/musl-cross-make.git (push)
